Core Viewpoint - The article highlights the innovative "ground heating" snow melting system implemented on the Ma-Zhao section of the Le-Xi Expressway, which is designed to enhance road safety and efficiency during winter conditions, particularly during the busy Spring Festival travel period [1][4]. Group 1: Technology and Innovation - The Ma-Zhao section is the first expressway in the province to adopt a large-scale ground heating snow melting system, featuring a closed-loop system that includes sensors, decision-making, and execution components [1][2]. - The system utilizes heat pipes buried 15 centimeters below the road surface, which are heated to 50-60 degrees Celsius to maintain road temperatures between 1-2 degrees Celsius, effectively melting snow [2][3]. - The snow melting system can melt 20 centimeters of snow in 5 hours at -10 degrees Celsius, demonstrating high efficiency even in extreme weather conditions [3]. Group 2: Performance and Efficiency - The system's energy consumption is notably low, with an estimated usage of only 0.06 kilowatt-hours per square meter per hour, which is 65% more energy-efficient than traditional electric heating methods [3]. - The heat pipes have a lifespan of 30 years and can withstand up to 50 million truck passes without affecting road integrity, ensuring long-term operational reliability [3]. Group 3: Operational Strategy - The expressway is equipped with multi-functional snow removal vehicles and has established a four-tier emergency response plan for varying snow conditions, ensuring continuous monitoring and maintenance during the Spring Festival [4]. - As of February 8, the average traffic flow on the Ma-Zhao section exceeded 3,000 vehicles, indicating the system's importance in managing high traffic volumes during adverse weather [4].
